Disposed along the chains 11 are brackets 19" pivotallycarrying'members havingr the arms 20, 21, and 95 V The' arms 20, 21.carry antifrictionrollers 23. l i' f f disposed in op- Ycounterweighting arms 22.

These rocha-ble arms are posing relation, and when not loaded, ex-

tend upwardlv. so that a charge; as a mass `100M'. .or ingot'of glass.may he .The weicht of, this charge overcomes thel 1 action of thecountcrweights 22, ithenvhy'v tt fra-:nv at the charge, it 1s gripped orrollers Q3 permit the charge me rntaticn whiie it is gripped andcomputed te essere placed thereonf tsr prcgrossing with 'this endless1105 less convcyer or pusher device. With these ingots 24 `cool enoughto have definite form and with their surfac s approaching'plasticity,this pushing together of thel succes'- sivejngots 24, may effect asealing'or welding therebetween to further assist in' having the mass a`unit for handlingand treatment V in the machine. y i

As the successive charges 24 are int-roduced, the doors or lids27 of thehousing 28 may be closed to more eiectivelyretain the A heat of thecharge in its movement throughr the mill.

On the shaft 2 of thevmotorll (Figs. 12)l` is the sprocket wheel 29having the'sproclretj,"4 Vchain 30 driving at a reduced speed thesprocket wheel 31 on the 'shaft' 32 carriedby 30 the brackets 33centrally of the frame 15. l, Following the housing' 28,- the mass ofglass is delivered to-the drum 34 (Figs. 6, 7), having near each endthereof'a flanged track 35 with which` coact thel sustaining. rollers435 36 on the parallel shafts 37 mounted in the brackets 38. The drum 34carries the annu:-

lar' set of gear teeth 39 in mesh with the gear 4()l fon the shaft 32vto rotate the drum 34.' Bracket`s41 on the inside of the drum l34 carryrollers 42 to coactfwith theglass mass ,to sustain the glass, and allowofits free progress, aswell as cause rotation thereof.`

Brackets 43 maintain an inner. shell 44 in position so that therollers42 extend therethrough, and the inner lining 45 fori this shell 44 of anon-conducting. substance serves to keen the heat of the charge from'objectionally affecting the bearings for the rollers 42.

The shell or heat conducting housing' 44 h'as the flare end 46 toreceive the hot. gases l from the flowing device 47 and conduct themalongr the approaching mass of glass to warm and have the mass fullypreheated when 1t enters the flowing device. These waste heat gases fromthe Howing device, not only pass through the shell 44, but are conductedalong through the housing 28 (Figs. 8,`9, 10, 11). L

` 'The pair of fuel supply mains 48 are provlded with manuallycontrolled valves 49 in the branches 50 extending to `the burners 5lhavmg'the series of perfora'tions 52 to supply a sheet or zone ofintense heat in :t blast tangentially of the /oncomin The manual controlof these `burners may bring the mass of vglass up to' the flowing stage,or `approximately thereto should the preheatng and waste gases not besuflicient tov the indicating instrument 56 controlling' resistance57 inthe circuit 58 to actuate the core 59- against the resistance of thespring 60, and thereby eect delicateadjustment gmass of glass..

These automatically controlled .burners or heaters, may beset forthe character of glass being treated to l,cause the desiredlmelting rate accbrding to' l the rate of progress of the massjrelatively tothe'heaiter and -according'to the'size of These burners,or in some instances one of the finished product to beI manufactured.`

ply. The glass as thus handled is`pcrmitted to take its new form freelyto the elimination of cording or introduction of internal strains' inreshaping, making an article' which may be true in lts form and soresistant in its structure as not to require even annealing. The articleis accordingly high grade in. all respects toanswer the demands.`uponsuch ware. z

Following the flowing device 47 carrying the fire resistant materlal inoperation ap-v proaching incandescent heatfwith the hot gases passingback along the oncoming ware,

is the air blast supply line 63 to the ring 64 directing a coolingmedium away from the Irestricted outlet of the heater ,to effect acurrent. away from the heater through the fixed drum 65 carried -by thebrackets v66. Through this drum housing 65 passes axially of said drum,the product 67, in this instance a tube. AThe supplied mass glass 24 hasan opening therethrough, which in usual opera# tion is alittle in excess'of the openingthrough the product.

Supporting this product 67 as it is early `cooled to maintain its-form,are the rollers 68 carried by the wheel 69 mounted in the bracket 70carried by the drum 65. The

ris

wheel 69 allows the lproduct to progress freely, while the rollers 68permit the product to' part-lclpate in the rotation of the glass.

Furthermore,`thel intensity of the Zone ac tioirof each burner may be Widely varied,not-only'by the blast pressure but as supplemented by valve opening 'andrich-y -ness of the fuel.` Therefore, a single .burner vor burnerl ionelmaybe effective in some manufacturingv or uses of'this mill. l,

As the'fiovvin'g glass has little cohesion, in instances where thesupplied massgisLrhtated. .it iswell tofmake provision'yforrotation ofthe product to keep torsion out ofthe soft product,l eliminateirregularities, and thereby-assist inthe manufacture of a high gradearticle.
